CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 450,680, dated April21, 1891.

Application filed January 21, 1891. Serial No. 878,615. (No model.)

To all whom it may concern;

Be it known that 1, PAUL S. N. PETERSEN, of Utica, in the county ofOneida and State of New York, have invented certain new and usefulImprovements in Oar-Couplers; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, referencebeing had to the accompanyingdraw ings, and to thefigures of reference marked thereon, which form part of thisspecification.

My invention relates to an improvement in carcouplers.

In the drawings which accompany and form a part of this specification,and in which similar numerals of reference refer to corresponding partsin both the figures, Figure 1 shows a top View of myimprovedcar-coupler. Fig. 2 shows avertical central longitudinal section of thesame.

Referring more specifically to the referencenumerals marked on thedrawings, 1 indicates the car-coupler head, which is attached to the carin the usual manner and is provided with rigid projecting forks 2 and 8.In fork 8 is pivoted at 5 coupling-hook at, which hook 4; is providedonits back with a cam-face 4., adapted to engage against movable block 6and also with a shoulder l adapted to become engaged against the side ofmovable block 6 and secure the coupling-hook 4. Block 6 is containedwithin a slot or recess 7 in the head and is free to move backward andforward in the slot, but is held to the front by follower 8 and spring9, acting on the follower. In the upper portion of the head is providedan enlargement 10, adapted to receive and contain the block 6 whenraised into uncoupled position. Follower S is mounted on a follower-arm12, and the spring 9 is coiled about the arm and retained between thefollower and the cross-wall 13 in the head. The forward movement of thefollower is lim ited by key 141- coming in contact with the cross-wall13.

11 indicates a chain attached to the block (3 and passing out of theopening in the top of the enlarged port-ion 10, and to the outer end ofchain 11 may be connected any further suitable connection devices foroperating th coupler.

15 indicates an opening in the end of the coupling-hook 4-, adapted toreceive an ordinary coupling-pin when it is desired to use this carcoupler in connection with an ordinary link.

The operation of the device is substantially as follows: The hook beingin the open position shown in dotted lines in Fig. l or a little fartheropen, in which it is held by the action of the spring 9 through thefollower and block 6 on the back of the cam-face r of the coupling-hook,when the two heads come together the coupling-hooks are forced from theposition shown in dotted lines to that shown in full lines, the block 6and follower 8 being forced back against the tension of spring 9 untilthe shoulder 4 passes by the edge of the block 6, when the block isforced forward by the spring and secures the coupling-hook in coupledposition. hen it is desired to uncouple the coupler, it is done bydrawing the block 6 up by means of chain 11 until the block is above theshoulder 45 of the hook 4-, when the hook is free to swing outward intoits open position.

What I claim as new, and desire to secure by Letters Patent, is

1. In a car-coupler, the combination of the coupler-head havingprojecting forks 2 and 3, the coupling-hook 4, pivoted in the arm 3, thevertical and horizontally-movable block 6, adapted to engage thecoupling-hook, and the spring-backing for the block, substantially asset forth.

2. The combination, in a car-coupler, of the head having forkedprojections 2 and 3, the coupling-hook 4, pivoted in the projection 3and having a cam-faced surface 4 and a shoulder r, the vertical andhorizontallymovable block 6, adapted'to engage the coupling-hook, thefollower, and the spring for actuating the follower, substantially asset forth.

The combination, in a car-coupler, of the coupler head having forkedprojections 2 and 3 and recesses 7 and 10 in the head, the coupling hookpivoted in arm 3 and having a camfaced back and a securing-shoulder, andthe securing-block horizontally movable in recess 7 and capable ofmovement into the recess 10, the follower for forcing the block towardthe coupling-hook and the connection with the block for raising it intothe upper portion of the head, substantially as set forth.

4. In a ear-coupler, the combination of the head having projections 2and 3, the coupling-hook pivoted in one of the projections, and thesecuring-block adapted to engage the couplinghook, the following devicefor forcing the block toward the coupling-hook, the securing-block beingcapable of removal from its position between the follower and.coupling-hook in uncoupling the device, substantially as set forth.

In Witness whereof I have affixed my sig-' nature in presence of twoWitnesses.
